Big retailers, from Best Buy to Target to Toys R Us, are engaging in a price war this holiday season, and shoppers can score some good deals if they know how to navigate them. But what's different this holiday season is that Best Buy and Target are matching online retailers such as Amazon.com for the first time. That's a big deal, since online prices tend to be lower than those in the store. (AP Photo/Jeff Chiu)
